W85 in an IDI info

i would normally reach out in the alternative fuel forum but i need help with my IDI. I have started running a W85 mix. i love it. its cheap and not that much more trouble.

on occasion the truck trys to run away with me. i mean it seems as if the truck has a turbo boost. it seems as if there is way more power from time to time. one man said it my be the thinner fuel but i don't know.

what say you....

Classic symptom of air intrusion. Have you done your tank pickups yet?

It's possible that your fuel blend is too thick.

Does it happen with pump diesel?

Mine has done the runaway deal since 1999 when using USDSL mostly.
After I went to WMO it was still there but less and less runaway percieved power.

I did it to me today but hardly alot for me.

May block the return line on the OEM filter head that connects with the injector caps.

I agree with Blind Driver. My W85 WMO is thicker than D2, and in colder weather it will surge and turn on the fuel filter light as it is having a harder time pulling the heavier viscosity WMO from the tank. When it starts that it has a "boost" syndrome also....

I agree with drinkypoo; I think its the strainer on the sending unit being broke, and pulling in air. Let me ask you this- does it do it when both tanks are full? or after you've put a couple of miles on it after fill up?

When I first got my 89, I was told that neither one of the gauges work, and to go by the mileage. When I cranked my pump all the way up, the truck went from 17 to 14, and I ran it out of fuel a couple of times...while still having about 6-10 gallons IN the tank. I also noticed small little black pieces of plastic in the sediment bowl of the filter. I believe this to be little pieces of the broken sender/ pick-up tube on the sending unit. Thats why I only get to use about 1/2 my tanks' capacity.

you ask if i have done my pickups yet. what do you mean?

i found chucks of rubber in my fuel lines and i removed the strainers in both tanks. i had to remove the switch directs the fuel from tanks. so i only have a rubber fuel line from the rear tank to the lift pump. as soon as my friends lift is clear of his camero i will lift it and redo the lines with steel.

it only does it when the tank is at above full.

w85 is thicker than diesel. but not by much. i have wondered if there are still pockets of gas that hits the injector pump and causes this. its is odd but i only worry because i might break the sound barrier and lift off the ground.

Guys i thank you for your help.
